Rojas scored one goal, did everything but get the scoresheet credit for another, and stood up big-time in a big occasion match at AAMI Park to help his A-League side to a 3-1 win.

With a contingent from English Premier League club Liverpool at the match to discuss a potential off-season game in Australia, as well as scouts from Italian giants Juventus, Rojas turned on his sensational best.

Postecoglou believes how the A-League's hottest property handled the pressure shows he has the right people guiding his career. And his coach believes he has developed the mental fortitude as well as the on-field ability to excel when he inevitably moves to Europe.

"There's obviously a lot of pressure on him, but I think he's got a pretty good network around him because, when you talk to him, he's not fazed by anything," Postecoglou said.

"That was a pretty big challenge for him with all the focus on him, and apparently there's a couple of thousand scouts out watching him.

"The fact he could perform like that shows if there were any question marks about him stepping up to a bigger stage, I think he answered them."

The win took Melbourne to second spot on the A-League ladder. But he now wants his side to chase down runaway leaders Central Coast Mariners.
